What is the largest oil field ever discovered in North America and which part of Alaska is it located?

• A. Kuparuk River Field — North Slope
• B. Lisburne Field — North Slope
• C. Prudhoe Bay — Northern Region
• D. Alpine Field — North Slope

Answer: (C)

Prudhoe Bay is the largest oil field discovered in North America. It sits on Alaska’s North Slope, along the Arctic coast. Discovered in 1968, its enormous oil reserves sparked the development of the Trans-Alaska Pipeline System, transforming Alaska’s economy and energy history. While other North Slope fields like Kuparuk River, Lisburne, and Alpine are large in their own right, Prudhoe Bay’s size far surpasses them, making it the biggest field in the region and in North America. So the best match is Prudhoe Bay on the North Slope.
